Question

Which statement can be made about waves A and B?

Wave A has a lower amplitude than Wave B.
Wave A has a higher amplitude than Wave B.
Wave A has a lower frequency than Wave B.
Wave A has a higher frequency than Wave B.

Answer 1

I can’t see the waves — could you upload the figure or describe them (how many cycles each completes in the same time, and their peak heights)?

Meanwhile, here’s how to tell which statement is correct from a graph:

- Amplitude: compare the maximum displacement from the central axis (equilibrium). The wave with the larger peak-to-equilibrium distance has the higher amplitude.
- If A’s peaks are smaller than B’s → “Wave A has a lower amplitude than Wave B.”
- If A’s peaks are larger → “Wave A has a higher amplitude than Wave B.”

- Frequency: compare how many complete cycles each wave makes in the same time interval (or compare wavelengths: shorter wavelength = higher frequency for the same wave speed).
- If A completes fewer cycles than B in the same time → “Wave A has a lower frequency than Wave B.”
- If A completes more cycles → “Wave A has a higher frequency than Wave B.”

Send the picture or describe peak heights and number of cycles and I’ll pick the correct statement.
